I Walk Away is a song from Phineas and Ferb The Movie: Across the 2nd Dimension, sung by Olivia Olson. It is played after Agent P leaves Phineas and Ferb, who have lost trust in him, to turn himself in to Heinz Doofenshmirtz.
I walk away
From you my friend
I hope that this
Is not the end
Of all the times we figured out
How to seize the day
And I walk away
- This is the shortest song in the movie, subverted with Kick It Up a Notch, which is the longest song in the movie.
- The song isn't on the Phineas and Ferb: Across the 1st and 2nd Dimensions soundtrack due to its short length.
